Hi Guys and Girls,
I have succesfully setup an exchange OWA SSL to SSL bridge through my ISA, and it works like a dream, apart from the initial speed, I have a 4mb lease line from the site ICM is fixed at 4mb. At home I have 2mb cable, and even with this speed the initial ISA connection seems a little slow to present the SSL cert and then displaying the OWA forms screen.
my questions are:-
1.) what are the users limits (rule of thumb) for the ammount of concurrent connections you should allow access to OWA through ISA.. user wise.
2.) Is there anything I am missing to speed up the connection a little, or anything I can watch to moniter response times.

It's all a littel bit "how long is a piece of string" - depends on your situation.
How many users? Depends. If you have 100 users all logged in to OWA but not actually doing anything at the time, there's zero load. But if just 10 of those users are simultaneously opening a 20Mb Excel attachment then there's significant load.
Your statements "initial speed" and "initial ISA conenction" seem to indicate that once logged in, everything's fine. As such I suspect either. a) problems resovling the external DNS name - poor/overloaded/misplaced/no-backup DNS servers b) listener responds quickly but slow/problem with internal authentication - see your internal AD/DNS infrastructure.
I have same problem with my OWA too. It would at least take 10 seconds for the certificate screen to show up. After entering userid/password, I will get to the OWA fast. I don't see any lag when the owa site is accessed from behind ISA. Probably I may have some issue because I got the certificate from my own CA. Let me know if you found any solution.
